Star Betelgeuse - A red supergiant in the constellation Orion

One fascinating star is Betelgeuse, a red supergiant located in the constellation Orion. Here are some intriguing facts about it: 1. Size and Volume: Betelgeuse is immense—if placed at the center of our solar system, it would extend past the orbit of Mars. 2. Variability: It is a pulsating variable star, meaning its brightness changes over time; it has been observed to vary in brightness over several months. 3. Life Cycle: Betelgeuse is nearing the end of its life cycle and is expected to explode as a supernova within the next million years, a relatively short time in astrophysical terms. 4. Distance: It is located approximately 640 light-years away from Earth. 5. Cultural Significance: Betelgeuse has been significant in many cultures and is commonly referred to as the “Shoulder of the Hunter” in the constellation Orion. 6. Color Indicator: Its reddish hue signifies a cooler surface temperature compared to other stars, which gives it a distinctive appearance. Betelgeuse con...

New collection of stars, not born in our galaxy, discovered in Milky Way

Astrophysicists announced the discovery of Nyx, a new collection of 250 stars that they believe are the remnant of a dwarf galaxy that merged with the Milky Way eons ago. The research combined massive cosmological simulations and observational data from the Gaia space observatory. It required large scale supercomputers and deep learning algorithms. The team plans to explore Nyx further using ground-based telescopes.
